Résumé: The most common source of renewable energy generation worldwide is wind turbines (WT) based on doubly-fed induction generators (DFIGs). To keep such sources connected to the grid during outages, low voltage ride-through (LVRT) capacity must be increased. Due to its vulnerability to grid disruptions, it is essential to follow stringent methods to keep DFIG connected to the grid. As a result, this study employs the crowbar resistance protection approach on a practical 2MW to improve WT’s LVRT. Under steady-state and symmetrical grid disturbances, the effectiveness of the DFIG-based WT with crowbar resistance is investigated and compared. The dynamic performance of the proposed scheme is analyzed to that of the existing capacitor bank system using a variety of metrics in order to demonstrate its efficacity. The modeling and simulation tools MATLAB and Simulink are used in this study. The findings reveal that the suggested LVRT capability outperforms the competition in practice
